In 1919, the notorious 'Peaky Blinders' are one of Birmingham, England 's most feared criminal gangs. Named after their practice of sewing razor blades into the peaks of their caps, the "Peaky Blinders" have interests in illegal betting, protection and the black market. Former war hero and brains behind the operation, Tommy Shelby, is eager to safeguard his family's success by making the business legitimate. But when he's offered a consignment of stolen arms, Tommy comes into direct conflict with Chief Inspector Campbell, a tough Belfast policeman who's been charged with recovering the guns at any cost.
